Q:
Simple interest on a certain sum is 16/25 of the sum. Find the rate percent and time, If both are numerically equal.
Answer & Explanation
Answer: B) Rate = 8% and Time = 8 years.
Explanation: Let sum = X. Then S.I = 16x/25
Let rate = R% and Time = R years.
Therefore, (x * R * R)/100 = 16x/25 => R = 40/5 = 8
Therefore, Rate = 8% and Time = 8 years.
